Description

L'invention concerne un dispositif de ventilation de l'habitacle d'un véhicule automobile, propre à introduire dans l'habitacle soit un flux d'air provenant de l'extérieur de l'habitacle, soit un flux d'air provenant de l'intérieur de celui-ci, encore appelé "air recyclé".The invention relates to a device for ventilating the passenger compartment of a motor vehicle, capable of introducing into the passenger compartment either a flow of air coming from outside the passenger compartment, or a flow of air coming from the inside of it, also called "recycled air".

Ainsi, lorsque le véhicule automobile traverse une zone particulièrement polluée, il est possible de ventiler l'habitacle avec de l'air non vicié prélevé à l'intérieur de celui-ci.Thus, when the motor vehicle passes through a particularly polluted area, it is possible to ventilate the passenger compartment with unclean air taken from inside.

On connaît déjà un dispositif de ventilation de l'habitacle d'un véhicule automobile, qui comporte une première entrée pour de l'air provenant de l'extérieur de l'habitacle, un premier volet contrôlant cette première entrée, une deuxième entrée pour de l'air provenant de l'intérieur de l'habitacle, un deuxième volet contrôlant cette deuxième entrée, une sortie d'air alimentée par la première entrée et la deuxième entrée, débouchant dans l'habitacle et logeant un groupe moto-ventilateur à vitesse réglable, ainsi qu'un organe de commande unique agissant sur le premier volet et le deuxième volet ainsi que sur la vitesse du ventilateur. Cet organe de commande unique permet donc à la fois de régler la position des volets et la vitesse du ventilateur.A device for ventilating the passenger compartment of a motor vehicle is already known, which comprises a first inlet for air coming from outside the passenger compartment, a first flap controlling this first inlet, a second inlet for the air coming from inside the passenger compartment, a second flap controlling this second inlet, an air outlet supplied by the first inlet and the second inlet, opening into the passenger compartment and housing a motorized fan group at speed adjustable, as well as a single control member acting on the first flap and the second flap as well as on the fan speed. This single control member therefore makes it possible both to adjust the position of the flaps and the speed of the fan.

Ce dispositif connu possède trois configurations de volets différentes : une configuration neutre, une configuration "air extérieur" et une configuration "air intérieur", encore appelée "air recyclé".This known device has three different shutter configurations: a neutral configuration, an "outside air" configuration and an "indoor air" configuration, also called "recycled air".

Dans la configuration neutre, le premier volet est dans une position de fermeture de la première entrée et le deuxième volet dans une position de fermeture de la deuxième entrée, le ventilateur étant réglé à vitesse nulle.In the neutral configuration, the first shutter is in a closed position for the first inlet and the second shutter in a closed position for the second inlet, the fan being set to zero speed.

Dans la configuration "air extérieur", le deuxième volet est dans une position de fermeture de la deuxième entrée, tandis que le premier volet est dans une position d'ouverture totale de la première entrée. Dans cette configuration, la vitesse du ventilateur peut être réglée, mais les positions respectives des deux volets restent inchangées.In the "outside air" configuration, the second shutter is in a position for closing the second inlet, while the first shutter is in a position for fully opening the first inlet. In this configuration, the fan speed can be adjusted, but the respective positions of the two flaps remain unchanged.

Dans la configuration "air intérieur", le premier volet est en position de fermeture de la première entrée, tandis que le deuxième volet est dans une position d'ouverture totale de la deuxième entrée. Dans cette configuration, la vitesse du ventilateur peut être réglée, mais les positions respectives des deux volets restent inchangées.In the "indoor air" configuration, the first shutter is in the closed position of the first inlet, while the second shutter is in a fully open position of the second inlet. In this configuration, the fan speed can be adjusted, but the respective positions of the two flaps remain unchanged.

Il en résulte que, si l'on souhaite passer de la configuration "air extérieur" à la configuration "air intérieur", ou inversement, il faut déplacer l'un des volets de sa position de fermeture à sa position d'ouverture totale et l'autre volet de sa position d'ouverture totale à sa position de fermeture, puis régler la vitesse du groupe moto-ventilateur.It follows that, if one wishes to pass from the "outside air" configuration to the "inside air" configuration, or vice versa, one of the flaps must be moved from its closed position to its fully open position and the other flap from its fully open position to its closed position, then adjust the speed of the motor-fan unit.

Il en résulte un temps de réponse élevé, d'autant plus que les volets sont généralement montés pivotants avec un angle de débattement important entre leurs positions de fin de course qui correspondent respectivement à la position de fermeture et la position d'ouverture totale.This results in a high response time, especially since the flaps are generally pivotally mounted with a large deflection angle between their end of travel positions which correspond respectively to the closed position and the fully open position.

L'invention a notamment pour but de surmonter les inconvénients précités.The object of the invention is in particular to overcome the aforementioned drawbacks.

C'est en particulier un but de l'invention de procurer un dispositif de ventilation du type précité qui diminue les temps de réponse à la commande lorsque l'utilisateur désire changer de configuration, c'est-à-dire de mode de distribution du flux d'air dans l'habitacle.It is in particular an object of the invention to provide a ventilation device of the aforementioned type which reduces response times to the command when the user wishes to change the configuration, that is to say the mode of distribution of the air flow in the passenger compartment.

L'invention propose à cet effet un dispositif de ventilation de l'habitacle, du type défini en introduction, ce dispositif comportant :

  • une configuration neutre dans laquelle le premier volet est dans une position de fermeture de la première entrée, tandis que le deuxième volet est dans une position de fermeture de la deuxième entrée, et que la vitesse du ventilateur est nulle;
  • plusieurs configurations "air extérieur" dans lesquelles le deuxième volet est en position de fermeture de la deuxième entrée tandis que le premier volet est déplacé progressivement d'une position d'ouverture partielle à une position d'ouverture totale de la première entrée et que la vitesse du ventilateur est progressivement augmentée; et
  • plusieurs configurations "air intérieur" dans lesquelles le premier volet est en position de fermeture de la première entrée, tandis que le deuxième volet est déplacé progressivement d'une position d'ouverture partielle à une position d'ouverture totale de la deuxième entrée, et que la vitesse du ventilateur est progressivement augmentée.
To this end, the invention proposes a device for ventilating the passenger compartment, of the type defined in the introduction, this device comprising:
  • a neutral configuration in which the first shutter is in a closed position for the first inlet, while the second shutter is in a closed position for the second inlet, and the fan speed is zero;
  • several "outside air" configurations in which the second shutter is in the closed position of the second inlet while the first shutter is gradually moved from a partially open position to a fully open position of the first inlet and the fan speed is gradually increased; and
  • several "indoor air" configurations in which the first shutter is in the closed position of the first inlet, while the second shutter is gradually moved from a partially open position to a fully open position of the second inlet, and that the fan speed is gradually increased.

Ainsi, dans les configurations "air extérieur", le premier volet peut prendre plusieurs positions différentes, tandis que dans les configurations "air intérieur", le deuxième volet peut prendre plusieurs positions différentes.Thus, in the "outside air" configurations, the first shutter can take several different positions, while in the "inside air" configurations, the second shutter can take several different positions.

Le passage d'une configuration "air extérieur" à une configuration "air intérieur" ou inversement s'effectue toujours en passant par la configuration neutre et par un déplacement progressif des deux volets.The transition from an "outside air" configuration to an "indoor air" configuration or vice versa is always carried out by passing through the neutral configuration and by a progressive displacement of the two flaps.

Il n'existe donc plus de temps morts lors de la commande du premier et du deuxième volets, comme c'était le cas dans la technique antérieure.There is therefore no more downtime when ordering the first and second flaps, as was the case in the prior art.

Dans une forme de réalisation préférée de l'invention, le premier volet et le deuxième volet sont chacun montés à pivotement autour d'un axe de rotation. Les axes de rotation respectifs du premier et du deuxième volet sont de préférence parallèles.In a preferred embodiment of the invention, the first flap and the second flap are each pivotally mounted about an axis of rotation. The respective axes of rotation of the first and second flap are preferably parallel.

Dans une forme de réalisation préférée de l'invention, le premier volet est déplaçable depuis la position de fermeture de la première entrée jusqu'à la position d'ouverture totale de la première entrée, et inversement, par rotations successives d'une fraction de tour chacune. De même, le deuxième volet est déplaçable de la position de fermeture de la deuxième entrée jusqu'à la position d'ouverture totale de la deuxième entrée, et inversement, par rotations successives d'une fraction de tour chacune.In a preferred embodiment of the invention, the first flap is movable from the closed position of the first entrance to the fully open position of the first entrance, and vice versa, by successive rotations of a fraction of turn each. Similarly, the second flap is movable from the closed position of the second entrance to the fully open position of the second entrance, and vice versa, by successive rotations of a fraction of a turn each.

Avantageusement, le premier et le deuxième volet sont disposés de telle sorte que, dans leurs positions de fermeture respectives, le premier et le deuxième volet sont éloignés tandis que, dans la position d'ouverture totale de la première entrée et dans la position d'ouverture totale de la deuxième entrée, le premier volet et le deuxième volet sont à chaque fois rapprochés.Advantageously, the first and the second flap are arranged so that, in their respective closed positions, the first and the second flap are separated while, in the fully open position of the first inlet and in the position of total opening of the second entrance, the first shutter and the second shutter are each time brought together.

Avantageusement, le dispositif comporte le même nombre de configurations "air extérieur", de configurations "air intérieur" et de vitesses du ventilateur. Ainsi, à chaque configuration "air extérieur" correspond une configuration symétrique "air intérieur" et une vitesse donnée du ventilateur.Advantageously, the device comprises the same number of "outside air" configurations, "inside air" configurations and fan speeds. Thus, to each "outside air" configuration corresponds a symmetrical "inside air" configuration and a given fan speed.

De préférence, la vitesse du ventilateur est réglable de façon discontinue, c'est-à-dire par incréments.Preferably, the fan speed is adjustable discontinuously, that is to say in increments.

Dans la description qui suit, faite seulement à titre d'exemple, on se réfère aux dessins annexés, sur lesquels :

  • la figure 1 est une vue en coupe partielle schématique d'un dispositif de ventilation selon l'invention représenté dans sa configuration neutre;
  • la figure 2 est une vue analogue à celle de la figure 1 montrant le même dispositif dans plusieurs configurations "air extérieur"; et
  • la figure 3 est une vue analogue à celle de la figure 1 montrant le même dispositif dans plusieurs configurations "air intérieur".
In the description which follows, given solely by way of example, reference is made to the appended drawings, in which:
  • Figure 1 is a schematic partial sectional view of a ventilation device according to the invention shown in its neutral configuration;
  • Figure 2 is a view similar to that of Figure 1 showing the same device in several configurations "outdoor air"; and
  • Figure 3 is a view similar to that of Figure 1 showing the same device in several configurations "indoor air".

On se réfère tout d'abord à la figure 1 qui représente un dispositif destiné à ventiler l'habitacle H d'un véhicule automobile. Le dispositif comprend une conduite 10 propre à prélever un flux d'air provenant de l'extérieur de l'habitacle (flèche F₁). Le conduit 10 alimente une première entrée 14 contrôlée par un volet 16 monté à pivotement autour d'un axe 18.We first refer to Figure 1 which shows a device for ventilating the passenger compartment H of a motor vehicle. The device comprises a line 10 suitable for taking a flow of air coming from outside the passenger compartment (arrow F₁). The conduit 10 feeds a first inlet 14 controlled by a flap 16 pivotally mounted around an axis 18.

Le dispositif comprend en outre un conduit 20 propre à recevoir un flux d'air provenant de l'habitacle H, c'est-à-dire un flux d'air recyclé (flèche F₂). Le conduit 20 alimente une deuxième entrée 22, qui est contrôlée par un deuxième volet 24 monté à pivotement autour d'un axe 26 qui s'étend parallèlement à l'axe 18 et à proximité de celui-ci. Les entrées 14 et 22 alimentent une sortie commune 28 qui débouche dans l'habitacle H. La sortie 28 constitue en même temps l'admission d'une enceinte 30 en forme de volute qui comporte une conduite de sortie 32. L'enceinte 30 loge intérieurement un groupe moto-ventilateur 34 comportant une turbine 36 propre à être entraînée en rotation par un moteur 38 à plusieurs vitesses. Dans l'exemple, le moteur 38 possède, en dehors d'une vitesse nulle, quatre vitesses différentes, le passage d'une vitesse à une autre se faisant par incréments successifs.The device further comprises a duct 20 adapted to receive a flow of air from the passenger compartment H, that is to say a flow of recycled air (arrow F₂). The conduit 20 feeds a second inlet 22, which is controlled by a second flap 24 pivotally mounted about an axis 26 which extends parallel to the axis 18 and close to the latter. The inputs 14 and 22 feed a common output 28 which opens into the passenger compartment H. The output 28 constitutes at the same time the admission of an enclosure 30 in the form of a volute which comprises an outlet pipe 32. The enclosure 30 houses internally a motor-fan unit 34 comprising a turbine 36 capable of being rotated by a motor 38 at several speeds. In the example, the motor 38 has, apart from a zero speed, four different speeds, the passage from one speed to another being done in successive increments.

Comme montré à la figure 1, la première entrée 14 et la deuxième entrée 22 sont situées en vis-à-vis l'une de l'autre en formant entre elles un angle voisin de 45°.As shown in Figure 1, the first inlet 14 and the second inlet 22 are located opposite one another, forming between them an angle close to 45 °.

Le dispositif de l'invention comprend en outre un organe de commande unique 40 comportant, dans l'exemple, un bouton rotatif 42 portant un index 44 déplaçable en regard d'une échelle graduée portant un repère "0".The device of the invention further comprises a single control member 40 comprising, in the example, a rotary button 42 carrying an index 44 displaceable opposite a graduated scale bearing a mark "0".

L'échelle comporte une plage 46 portant des repères 1, 2, 3 et 4, disposés dans le sens horaire à partir de la position 0 et correspondant à des configurations "air extérieur" ainsi qu'une plage 46' portant des repères 1, 2, 3 et 4, disposés dans le sens anti-horaire à partir de la position 0, et correspondant à des configurations "air intérieur".The ladder comprises a range 46 carrying marks 1, 2, 3 and 4, arranged clockwise from position 0 and corresponding to "outside air" configurations, as well as a range 46 ′ bearing marks 1, 2, 3 and 4, arranged anti-clockwise from position 0, and corresponding to "indoor air" configurations.

Le bouton rotatif 42 peut être amené dans l'une ou l'autre des neuf positions mentionnées précédemment. L'organe 40 commande simultanément le déplacement des volets 16 et 24 par l'intermédiaire d'une liaison mécanique ou électrique 48 connue en soi, ainsi que la vitesse du moteur 38 du ventilateur 34 par l'intermédiaire d'une liaison électrique 50. Le ventilateur est à vitesse nulle lorsque l'index 44 est en regard du repère 0 et il tourne à une première vitesse V₁, à une deuxième vitesse V₂ plus élevée, à une troisième vitesse V₃ encore plus élevée et à une vitesse maximale V₄ lorsque l'index 44 se trouve respectivement en regard de l'un ou l'autre des repères 1, des repères 2, des repères 3 et des repères 4.The rotary button 42 can be brought into one or other of the nine positions mentioned above. The member 40 simultaneously controls the movement of the flaps 16 and 24 via a mechanical or electrical connection 48 known per se, as well as the speed of the motor 38 of the fan 34 via an electrical connection 50. The fan is at zero speed when the index 44 is opposite the reference 0 and it rotates at a first speed V₁, at a second higher speed V₂, at a third speed V₃ even higher and at a maximum speed V₄ when l the index 44 is located respectively opposite one or the other of the marks 1, the marks 2, the marks 3 and the marks 4.

Le dispositif peut prendre une première configuration, appelée "configuration neutre", dans laquelle le premier volet est dans une position P₀ de fermeture de la première entrée 14 et le deuxième volet 24 dans une position P'₀ de fermeture de la deuxième entrée 22 (figure 1). Dans cette configuration, les volets 16 et 24 sont éloignés l'un de l'autre et forment entre eux un angle voisin de 45°. Cette position est obtenue en plaçant l'index 44 du bouton 42 en regard du repère 0, le ventilateur étant réglé sur une vitesse nulle. L'habitacle H ne peut recevoir ni de l'air provenant de l'extérieur, ni de l'air provenant de l'intérieur.The device can take a first configuration, called "neutral configuration", in which the first flap is in a position P₀ for closing the first inlet 14 and the second flap 24 in a position P'₀ for closing the second inlet 22 ( figure 1). In this configuration, the flaps 16 and 24 are distant from each other and form between them an angle close to 45 °. This position is obtained by placing the index 44 of the button 42 opposite the reference 0, the fan being set to zero speed. Passenger compartment H cannot receive air from the outside or air from the inside.

Le volet 16 est déplaçable de la position P₀ vers plusieurs positions successives P₁, P₂, P₃, P₄ (figure 2), le passage d'une position à une autre se faisant à chaque fois par rotation d'une fraction de tour.The flap 16 is movable from position P₀ to several successive positions P₁, P₂, P₃, P₄ (Figure 2), the passage from one position to another being done each time by rotation of a fraction of a turn.

Dans la position P₁, le premier volet 16 ouvre partiellement l'entrée 14 et dans la position P₄, le volet 16 ouvre totalement l'entrée 14. Le passage de la position P₀ à P₄ ou inversement correspond à un débattement angulaire du volet sensiblement égal à 45°.In the position P₁, the first flap 16 partially opens the inlet 14 and in the position P₄, the flap 16 fully opens the inlet 14. The transition from the position P position to P₄ or vice versa corresponds to a substantially equal angular movement of the flap at 45 °.

Le second volet 24 est déplaçable de la position P'₀ de fermeture de la deuxième entrée 22 vers plusieurs positions d'ouverture successives P'₁, P'₂, P'₃, P'₄, (figure 3). Dans la position P'₁, le volet 24 ouvre partiellement l'entrée 22 et dans la position P'₄ il ouvre totalement l'entrée 22. Le débattement angulaire du volet entre ces deux positions extrêmes est sensiblement égal à 45°. Il est à noter que les volets 16 et 24 sont rapprochés lorsque le volet 16 est en position P₄ et le volet 24 en position P'₀ (figure 2) et lorsque le volet 16 est en position P₀ et le volet 24 en position P'₄ (figure 3).The second flap 24 is movable from the position P'₀ for closing the second inlet 22 to several successive opening positions P'₁, P'₂, P'₃, P'₄, (Figure 3). In the P'₁ position, the flap 24 partially opens the inlet 22 and in the P'₄ position it fully opens the inlet 22. The angular movement of the flap between these two extreme positions is substantially equal to 45 °. It should be noted that the flaps 16 and 24 are brought together when the flap 16 is in the P₄ position and the flap 24 in the P'₀ position (Figure 2) and when the flap 16 is in the P₀ position and the flap 24 in the P 'position ₄ (figure 3).

On comprendra que dans la position P₁ ou P'₁, la position P₂ ou P'₂, la position P₃ ou P'₃, et la position P₄ ou P'₄, le ventilateur tourne respectivement à une vitesse V₁, V₂, V₃ et V₄, avec V₁ < V₂ < V₃ < V₄.It will be understood that in the position P₁ or P'₁, the position P₂ or P'₂, the position P₃ or P'₃, and the position P₄ or P'₄, the fan rotates respectively at a speed V₁, V₂, V₃ and V₄, with V₁ <V₂ <V₃ <V₄.

Pour passer de la configuration neutre (figure 1) aux configurations "air extérieur" (figure 2), il suffit de tourner le bouton 42 dans le sens horaire pour amener l'index 44 en regard du repère 1, 2, 3 ou 4 désiré, ce qui assure le déplacement progressif du volet 16 et l'augmentation progressive de la vitesse du ventilateur. Dans la position P₄ de pleine ouverture de l'entrée 14, le volet 16 permet un débit d'air maximal à travers l'entrée 14 et le ventilateur tourne à sa vitesse maximale.To go from the neutral configuration (Figure 1) to the "outside air" configurations (Figure 2), simply turn the button 42 clockwise to bring the index 44 next to the desired mark 1, 2, 3 or 4 , which ensures the progressive displacement of the flap 16 and the progressive increase in the speed of the fan. In the position P₄ of full opening of the inlet 14, the flap 16 allows a maximum air flow through the inlet 14 and the fan rotates at its maximum speed.

Si l'on désire ensuite placer le dispositif dans une configuration "air intérieur", il suffit de faire tourner le bouton 42 dans le sens anti-horaire pour que l'index 44 vienne en regard du repère 1, 2, 3 ou 4 désiré des configurations "air intérieur", en passant par la configuration neutre.If it is then desired to place the device in an "indoor air" configuration, it suffices to rotate the button 42 anti-clockwise so that the index 44 comes opposite the desired mark 1, 2, 3 or 4 "indoor air" configurations, passing through the neutral configuration.

Au-delà de la position neutre, le volet 24 pivote de la position P'₀ à la position P'₁ (figure 3) et peut être amené ensuite successivement dans les positions P'₂, P'₃ et P'₄. Dans cette dernière position, le flux d'air intérieur est maximal et la vitesse du ventilateur est également maximale.Beyond the neutral position, the flap 24 pivots from the P'₀ position to the P'₁ position (Figure 3) and can then be brought successively to the P'₂, P'₃ and P'₄ positions. In this last position, the interior air flow is maximum and the fan speed is also maximum.

On comprendra que les volets 16 et 24 peuvent adopter neuf positions différentes et que le passage d'une position à une autre s'effectue de façon progressive en faisant pivoter un seul des deux volets, et cela sur une fraction de tour, tout en faisant varier progressivement la vitesse du ventilateur. De ce fait, il n'existe pas de temps morts à la commande et le passage d'une configuration "air extérieur" à une configuration "air intérieur" ou inversement s'effectue de manière très rapide.It will be understood that the flaps 16 and 24 can adopt nine different positions and that the transition from one position to another is carried out gradually by rotating only one of the two flaps, and this for a fraction of a turn, while making gradually vary the fan speed. As a result, there is no idle time when ordering and the transition from an "outside air" configuration to an "indoor air" configuration or vice versa takes place very quickly.

Il est bien entendu que l'invention n'est pas limitée à la forme de réalisation décrite précédemment et qu'elle s'étend à d'autres variantes.It is understood that the invention is not limited to the embodiment described above and that it extends to other variants.

Ainsi, au lieu de prévoir un réglage incrémental des deux volets et de la vitesse du ventilateur, on pourrait prévoir un réglage continu.Thus, instead of providing an incremental adjustment of the two flaps and of the fan speed, one could provide a continuous adjustment.
